Apache配置虚拟主机

在一个Apache服务器上可以配置多个虚拟主机，实现一个服务器提供多站点服务，其实就是访问同一个服务器上的不同目录。Apache虚拟主机配置有3中方法：基于IP配置、基于端口配置，基于主机名配置。本文中Apache版本为2.4.28，主机版本是CentOS 6.9，由于是编译安装，其安装路径是/usr/local/apache/，配置文件在/etc/httpd/目录下，DocumentRoot和Directory路径为/www/htdocs/，主机ip地址为172.16.8.11/24，selinux和iptables已关闭

配置虚拟主机前的准备：
1.启用vhosts
编辑主配置文件，找到 #Include /etc/httpd/extra/httpd-vhosts.conf这一行，把前面的#号去掉，然后重读配置文件

[root@localhost ~]# vim /etc/httpd/httpd.confInclude /etc/httpd/extra/httpd-vhosts.conf[root@localhost ~]# service httpd reload

2，创建虚拟主机存放的根目录，3个测试页面

[root@localhost ~]# mkdir -p /vhosts/{web1,web2,web3}/htdcos[root@localhost ~]# vim /vhosts/web1/htdcos/index.htmlPage at web1[root@localhost ~]# vim /vhosts/web2/htdcos/index.htmlPage at web2[root@localhost ~]# vim /vhosts/web3/htdcos/index.htmlPage at web3

一，基于ip配置虚拟主机
主机ip地址为172.16.8.11/24，在eth0网卡上额外添加2个ip地址

[root@localhost ~]# ip addr add 172.16.8.12/24 dev eth0 [root@localhost ~]# ip addr add 172.16.8.13/24 dev eth0 

编辑虚拟主机配置文件，添加如下内容

[root@localhost ~]# vim /etc/httpd/extra/httpd-vhosts.conf 

<VirtualHost 172.16.8.11:80>    ServerName web1.example.com    DocumentRoot "/vhosts/web1/htdocs"    <Directory "/vhosts/web1/htdocs">        Options Indexes FollowSymLinks        AllowOverride None        Require all granted    </Directory></VirtualHost><VirtualHost 172.16.8.12:80>    ServerName web1.example.com    DocumentRoot "/vhosts/web2/htdocs"    <Directory "/vhosts/web2/htdocs">        Options Indexes FollowSymLinks        AllowOverride None        Require all granted    </Directory></VirtualHost><VirtualHost 172.16.8.13:80>    ServerName web1.example.com    DocumentRoot "/vhosts/web3/htdocs"    <Directory "/vhosts/web3/htdocs">        Options Indexes FollowSymLinks        AllowOverride None        Require all granted    </Directory></VirtualHost>

重载httpd配置文件

[root@localhost ~]# service httpd reload

在浏览器上依次输入172.16.8.11，172.16.8.12，172.16.8.13
得到的结果依次为Page at web1，Page at web2，Page at web3

二，基于端口配置虚拟主机
编辑主配置文件，在Listen 80下添加2行

[root@localhost ~]# vim /etc/httpd/httpd.confListen 8008Listen 8080

修改虚拟主机配置文件

[root@localhost ~]# vim /etc/httpd/extra/httpd-vhosts.conf 

<VirtualHost 172.16.8.11:80>    ServerName web1.example.com    DocumentRoot "/vhosts/web1/htdocs"    <Directory "/vhosts/web1/htdocs">        Options Indexes FollowSymLinks        AllowOverride None        Require all granted    </Directory></VirtualHost><VirtualHost 172.16.8.11:8008>    ServerName web1.example.com    DocumentRoot "/vhosts/web2/htdocs"    <Directory "/vhosts/web2/htdocs">        Options Indexes FollowSymLinks        AllowOverride None        Require all granted    </Directory></VirtualHost><VirtualHost 172.16.8.11:8080>    ServerName web1.example.com    DocumentRoot "/vhosts/web3/htdocs"    <Directory "/vhosts/web3/htdocs">        Options Indexes FollowSymLinks        AllowOverride None        Require all granted    </Directory></VirtualHost>

重启httpd服务

[root@localhost ~]# service httpd restart

在浏览器上依次输入172.16.8.11，172.16.8.11:8008，172.16.8.11:8080
得到的结果依次为Page at web1，Page at web2，Page at web3

三，基于主机名配置虚拟主机
修改虚拟主机的配置文件

[root@localhost ~]# vim /etc/httpd/extra/httpd-vhosts.conf 

<VirtualHost 172.16.8.11:80>    ServerName web1.example.com    DocumentRoot "/vhosts/web1/htdocs"    <Directory "/vhosts/web1/htdocs">        Options Indexes FollowSymLinks        AllowOverride None        Require all granted    </Directory></VirtualHost><VirtualHost 172.16.8.11:80>    ServerName web2.example.com    DocumentRoot "/vhosts/web2/htdocs"    <Directory "/vhosts/web2/htdocs">        Options Indexes FollowSymLinks        AllowOverride None        Require all granted    </Directory></VirtualHost><VirtualHost 172.16.8.11:80>    ServerName web3.example.com    DocumentRoot "/vhosts/web3/htdocs"    <Directory "/vhosts/web3/htdocs">        Options Indexes FollowSymLinks        AllowOverride None        Require all granted    </Directory></VirtualHost>

重载httpd配置

[root@localhost ~]# service httpd reload

修改浏览器所在的系统hosts文件（Windows路径是C:\Windows\System32\drivers\etc\hosts，Linux路径是/etc/hosts），添加如下3行

172.16.8.11 web1.example.com172.16.8.11 web2.example.com172.16.8.11 web3.example.com

在浏览器上依次输入web1.example.com，web2.example.com，web3.example.com
得到的结果依次为Page at web1，Page at web2，Page at web3

以上三种配置虚拟主机的方式可以混合使用
